In its largest renewable energy shopping spree ever, PacifiCorp has shortlisted nearly 4,000 MW of new wind, solar and battery storage resources across its multistate service territory in the western United States to come online by the end of 2024.
The utility subsidiary of Warren Buffett’s Berkshire Hathaway Energy is eying 19 projects to supply enough power for approximately one million homes across its Pacific Power division in Washington, Oregon and California, as well as its Rocky Mountain Power division in Idaho, Utah and Wyoming.
“The results of this competitive all-source [request for proposals] deliver the best new resources the West has to offer and will enable our customers and communities across the West to benefit from low-cost clean energy to grow their economies and run their businesses and homes,” Rick Link, PacifiCorp’s vice president of resource planning and acquisitions, said in a June 16 statement.
“This is the biggest [request for proposals] in our company’s history,” PacifiCorp spokesperson Dave Eskelsen added in a June 17 interview.
The envisioned projects stem from a solicitation in July 2020, issued in line with PacifiCorp’s 2019 integrated resource plan, and come as utilities throughout the West seek to decarbonize their power portfolios and build out transmission to access and share renewable energy resources.
Submitted to the Oregon Public Utility Commission on June 15, the short list includes 1,641 MW of wind generating capacity in Wyoming, 151 MW of wind in Idaho, 1,243 MW of solar power in Utah and 210 MW of solar in Oregon. The Utah and Oregon solar projects are paired with 535 MW of battery storage. PacifiCorp is eyeing another 200 MW of stand-alone storage in Utah as well.
